9). Working humidity: 5% ~ 95% RH
10). Size: 44 x 20 x 14 mm.
3. Connection method:
1).IN+: input positive
2) IN-: input negative pole.
Out+: output positive
Output: output negative pole.
4. Instructions:
1) First connect the cable between the module and the power supply, and then turn on the power supply. (When the input port is under voltage and wired, it may easily cause sparks, especially if the input voltage is high even burn the pads of the module).
2) For the first use, you need to connect to a power supply of more than 30 V and measure with a multimeter or voltmeter whether the output voltage of the module matches the voltage required by the device.
3) The electrical equipment (load) is connected to the output end of the module.
5. Package contents:
1) 1 x DC downward module.
